DRY-KILN TRUCK.

SPECIFICATION forming part of Letters Patent No. 734,057, dated Jury 2i; 190s. Application led January 3, 1901. Serial No. 41,944. (No model.)

.To @ZZ whom it may concern.-

Beit known that I, HERBERT B. GILLETTE, a citizen of the United States, residing at the city of Benton Harbor, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Dry-Kiln Trucks, of which the following is a specification.l

This invention relates to improvements in lumber-trucks for dry kilns. These trucks are designed and intended for carrying heavy loads. It is therefore desirable that they be made-of the maximum strength for a given weight of material and that the friction of the bearing-Wheels be reduced to the minimum.l It is also necessary that these structures be very simple and cheap and economical to manufacture on account of the large number required to be used to successfully support the immense loads placed upon them.

The objects of this invention are, therefore, to provide a practical and efficient structure utilizing angle steel or iron, which is probably the best adapted for the purpose, to provide a simple and edicient structure in which a roller-bearing is utilized, to provide a satisfactory structure in which a comparatively large wheel can be easily utilized, and to provide a structure in which end stakes or posts can be readily and easily inserted or'removed, thus avoiding the necessity of specially-constructed trucks where end stakes or posts are desired.

Further objects will delinitely appear in the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in this specification.

The inventiouis clearly defined and pointed out in the claims.

A structure embodying the essential features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which- Figure l is a side elevation of a structure embodying the features of my invention. Fig. 2 is an inverted plan View of a drykiln truck embodying the features ot' my invention. Fig. 3 is an enlarged detail transverse sectional elevation taken on a line corresponding to line 3 3 of Figs. l and 2. Fig. 4 is a side elevation of one of the wheels removed from the machine and the end plate removed, the rollers and axle being left in position. Fig. 5 is a transverse enlarged detail sectional elevation taken on a line corresponding to line 5 5 of Figs. 1 and 2. Fig. G is an inside` elevation view of one of the end plates E, showing the engaging lugs or flanges n'.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines,

and similar letters of reference refer to similar parts throughout the several views.

Referring tothe lettered parts of the drawings, A A are the side rails of a truck, which are of angle steel or iron, preferably steel, with the angle outside toward the top. These are secured together by cross-brackets I I toward the center and F F at each end. These brackets are preferablyy made of malleable iron, though of course any suitable material may be employed. These are preferably riveted to the side pieces A. The end brackets or cross-pieces F F are made to form a socket down through the middle, as clearly appears in Fig. 5, toreceive a stake or post at that point, which can be readily removed when desired. Downwardly-projecting brackets B B are securely riveted to the vertical limb of the angle-irons A at each side. An axle D extends through these and is secured in position by Cotter-pins c c or by other suitable means. The wheel C is carried on this axle D, the bore being large enough to permit of theinterposition of the rollers ct, which extend substantially from end t'o end of the hub of the wheel and are of even size from` end to end. The ends of the hub are faced smooth and flat at right angles to the axis thereof, and notches n n, 'n are formed at intervals around the same. End plates E are provided having projecting lugs n n n to engage the recesses on the ends of the hubs, the inner face being made true and smooth and the outer face being planed smooth at right an-r gles to the axisof the wheel. These end plates E are retained in position between the brackets B B. The axle D is supported by the bearing-rollers c, and serves as a tie-rod to hold the vertical limbs of the angle-iron A exactly in parallel vertical position, where they will exert their greatest strength. The Wheel C Vis of course suitably grooved or provided with a tread to fit on the usual rail for use in this connection.

Having thus described my improved drykiln truck, I desire to state that it can be considerably varied in its details without departing from my invention. The improved wheel with the roller-bearings is especially adapted for use in this combination and could be used with other constructions of frames. The structure of frame is particularly economical of material and could of course be used in connection with Wheels not having a rollerbearing, though the particular structure of wheel and bearing is especially adapted for use in this frame. The end brackets are available in many dilerent styles of dry-kiln trucks. I have shown a simple means of retaining the end plates on the roller-bearings; but such end plates might be otherwise supported and be very effective.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1'. In a dry-kiln truck, the combination of theframe made up of angle-irons A, A, one at each side with the angles at the upper outer side; brackets I, I, connecting the same together toward the center; and brackets F, F, containing sockets toward each end; downwardly -depending brackets B, B, secured to the vertical limbs of the side pieces A with an axle D connecting them together below; a wheel C on said axle; bearing-rollers a,chambered in the wheel and extending from end to end of the hub thereof; end plates E, E, with lugs n', n', fitting into recesses in the ends of the hub to guide and retain the rollers in position being themselves retained between the brackets B, B, all coactingsnbstantially as described for the purpose specied.

2. In a dry-kiln truck, the combination of the frame made up of angle-irons A, A, rightangled in cross-section; one at each side with the angles at the upper outer side; brackets I, I, connecting the same together toward the center; and brackets F, F, containing sockets toward each end; downwardly-depending brackets B, B, secured to the vertical limbs of the side pieces A with the axle D connecting them together below; a Wheel C on said axle; bearing-rollers a, chambered in the Wheel and extending from end to end of the hub thereof; end plates to guide and retain the rollersin position being themselves retained between the brackets B, B, all coacting substantially as described for .the purpose specified.

3. In a dry-kiln truck, the combination of the frame made up of angle-irons right angled in cross-section; one at each side with the angle at the upper outer side; brackets connecting the same toward the center; brackets containing sockets toward each end; depending brackets secured to the vertical limbs of the said side pieces, with an axle connecting them together below; a wheel on said axle; bearing-rollers chambered in said wheel and extending from end to end of the hub thereof; end plates to guide and retain the rollers in position, as specified.

4. In a dry-kiln truck, the combination of the frame made up of angle-irons one at each side; brackets connecting the same together; brackets B, B, with an axle connecting them together; a wheel on said axle; bearing-rollers chambered in the wheel and extending from end to end of the hub thereof; end plates E, E, with lugs n', n', fitting into recesses in the ends of the hub to guide and re tain the rollers in position being themselves retained between thebrackets B, B, as specied.

5. In a dry-kiln truck, the combination of the frame made up of angle-irons right-angled in cross-section; one at each side with the angle at the upper outer side; brackets connecting the same together; brackets B,B,with an axle connecting them together, a wheel on said axle; bearing-rollers chambered in the wheel and extending from end to end of the hub thereof; end plates to guide and retain the rollers in position being themselves retained between the brackets B, B, as specified.

6. In a dry-kiln truck the combination of the frame made up of angle-irons, right-angled in cross-section, arranged at each side with the angle at the upper outer side; brackets connecting the same together and fitting into the angle; brackets extending down from the vertical limbs and connected by suitable axles; and wheels on the said axles coacting for the purpose specified.

In Witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
